It's official
Nintendo has made a hardware revision to the Wii DVD drive circuit board that blocks all current D2C mod chips from working.
Reports on other forums have people stating they have tried ARGON, D2Pro and Wassabi and none work. (I have not heard if D2CKEY works but i assume no)
The Drive Chip is still called the GC2-D2C but what i have noticed is that the second row of numbers normally underneath that line is no longer present.
I tried installing a ARGON in a new wii last night and when it didn't work i found a few posts that these are turning up so I figured i would get a thread started here to warn people as well.
So LU567xxxxxxx = BAD!!!! AVOID!! Other serial number ranges are sure to come.
I am hoping that Infectus will be first to come out with firmware for these new drives as i just ordered a bunch of ARGONS.
And now for some pictures..
